Nelson is right but a bit more explanation is needed.

The mixer tracks in later versions of BIAB have the feature of the track name following the instrument assigned to the track. However, each track has a legacy name as detailed by Nelson.

(B)bass
(P)piano
(D)drums
(G)guitar
(S)strings (ooh's assigned to this track)
Melody
Soloist
(Audio)

If you want to have only the ooh's playing in certain bars using the method Wish is attempting,
c...cdv where only the bass, drums and vocals are heard, you must use the legacy names.
d - drums; B - Bass are correct but the V - is incorrect. In the above example use C...bds and the song should play all the correct parts because you are telling BIAB to play the Strings track where the vocals are located. It did on my system when I tested it this morning.

Alternately, you can also mute certain tracks using the Bar Settings. Mute All Instruments and the select Return To Normal for the Bass, Drums and Vocals. At the bar you want all of the instruments to begin playing, In Bar Settings, change Mute All Instruments to Return To Normal.
